Springer is not your Average Autobot.
One minuite he's layzing around.
The next he's flirting with Arcee.
Then the next thing you know,you see a "British Racing Green" colored Blur with weapons ablaze speeding past you.

On special request He retains his cybertronian mode because earth vehicles won't support both his Car and Helijet vehicle modes........................But that didn't stop him from requesting a green paint job

His vehicle modes were designed by Springer himself as they can each fit one human.

despite his Rude and Lazy Behaivior,the only reason he hasn't been kicked out of Nest is because. When surrounded by Decepticons You can Promise ,with him by your side you will make it out alive.
